CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 253,037, dated January31, 1882.

Application filed July 25, 1881. (ModeL) To all whom it may concern:

Be it known that I, JAMES L. GRIFFIN, of Cusseta, in the county of Cassand State of Texas, have invented a new and Improved Oar- Goupling, ofwhich the following is a specification.

The object of my invention is to provide a new and improved device forcoupling cars automatically.

The invention consists in a lever pivoted in the front of the top of thedraw-head and provided at its outerend with an aperture, through whichthe coupling-pin is passed into the aperture in the draw-head, belowwhich lever anotherleveris pivoted, hanging vertically across the frontopening of the draw-head, and provided at the upper part of its inneredge with a projection, so that when the coupling-link pushes the lowerlever inward the upper lever and the pin are raised, and drop as soon asthe link has passed into the draw-head. The drawhead is provided withtwo apertures atthe sides for the coupling-pin when thesameis not inuse. The coupling-pin has an annular recess directly below the flattenedhead, for the purpose of re-' taining this coupling-pin in the apertureofthe pivoted lever.

In the accompanying drawings, Figure 1. is a plan view of my improvedcar-coupling. Fig. 2'is a longitudinal sectional elevation of the sameon the line x 00, Fig. 1. Fig. 3 is a cross-sectional elevation of thesame onthe line 3 3 Fig. 1. Fig. 4 is a longitudinal elevation of thecoupling-pin. Fig. 5 is a detail plan view of the free end of the levercarrying the coupling-pin.

Similar letters of reference indicate corre-' sponding parts.

A lever, A, is pivoted to the top of the front of the draw-head B, andrests in a slot, 0, in the top of the draw-head. The free end of thislever A is provided. with a transverse aperture, D, through which thecoupling-pin E is passed into its vertical aperture F in the draw-head,the head J of the pin resting on the end of the lever A. Thiscoupling-pin E is made flat, and has a flat head, J, and an annularrecess, J, directly below this head. The aperture F in the draw-head islongitudinal, so as to admit the pin E. A lever, Gr, provided at theupper end of its inner edge with a projection, H, is pivoted to thedraw-head B directly below the pivot of the lever A.

The draw-head is provided with two apertures, K, in projections L of thesides of the draw-head, for the purpose of receiving the pin E when thesame is not in use.

The operation is as follows: The lever A is raised, the pin E is passedthrough the slot D and then turned, so that the pin E can enter theaperture in the draw-head, and the pin E and head J will be at rightangles to the slot D. The shoulder formed by the recess J prevents thepin from being drawn out of the slot D when in this position, and canonly be removed if it is turned to be parallel with this slot. 1f theend of the lever A is thrown up suddenly, the coupling-pin E cannot flyout, as it would if not provided with devices for holding it in itsaperture. Whenthe link M is in the draw-head the several parts are inthe positions shown. As the link enters the drawheadvit pushes the leverG inward, causing the projection H to raise the lever A and the pin E,as shown in dotted lines in Fig. 2. When the link has passed into thedraw-head as far as the aperture F the lever Gr slips from the front endof the link and swings to the front, thus permitting the lever A and thepin E to drop, the latter dropping through the link, andthusholdingthesameinthedraw-head. When the link is withdrawn from thedraw-head the lever G swings to the front, permitting the link to pass.

Having thus fully described my invention, 1 claim as new and desire tosecure by Letters Patent- 1. The combination, with the draw-head in acar-coupling, of the lever A, pivoted in the front of draw-head, the pinE, suspended in a slot, D, of said lever, and the lever G, having theprojection H, the whole adapted to operate in connection with the link,as described.

2. The coupling-pin E, constructed, substantially as herein shown anddescribed, with a flat head, J, and an annular recess, J, directly JAMESLEE GRIFFIN.
